Description

Technical Field

[0001] This utility model relates to the field of raw material screening technology, specifically to a raw material screening device for the production of tateretrelin tablets. Background Technology

[0002] In pharmaceutical manufacturing, the particle size, purity, and uniformity of raw materials directly determine the quality stability and clinical efficacy of the final drug, and are core control elements in formulation production. For tatirelin tablets, a drug formulation with stringent dosage precision requirements, the quality of raw material sieving is particularly critical. Precise sieving is essential to ensure that the particle size of the raw materials meets the specific process standards for tablet compression. This guarantees that key indicators such as tablet compression quality, disintegration performance, and dissolution meet standards, avoiding fluctuations in efficacy or medication safety risks caused by uneven particle size. Patent specification CN207681020U discloses a tablet sieving device, including a top-opening collection box with a hopper at the bottom and a collection bag at the bottom outlet of the hopper. Inside the collection box, two sliding collection trays are arranged vertically via slide rails. A screen is installed on the bottom surface of each collection tray, and a top rod is installed on the rear end face of each tray, extending through the rear end face of the collection tray. A vertical rotating shaft is located at the rear end of the collection tray, with cams mounted at its upper and lower ends. The cams abut against the rear end of the corresponding top rod, and a motor connected to the rotating shaft is located on the rear end face of the collection tray. A spring is installed on the front end face of each collection tray, and a corresponding door plate is installed on the front end face of the collection tray, with the spring abutting against the corresponding door plate. During tablet sieving, this device reduces labor intensity, ensures thorough sieving, and eliminates the need to stop the pharmaceutical machine during tablet transfer, maintaining production cycle time and improving operational efficiency.

[0003] However, this technical solution has significant limitations: while it can achieve residue screening and efficiency improvement, it cannot adjust the filter pore size. In the production of tatirelin tablet raw materials, different batches and different process stages often require screening of raw materials with different particle sizes. Screens with fixed filter pores are difficult to adapt to the needs of multi-size screening, requiring frequent replacement of the entire collection box or screen. This not only increases operational complexity and downtime but may also affect screening accuracy due to disassembly and assembly errors during replacement, and is more likely to cause raw material residue and cross-contamination risks, failing to meet the flexibility and high-precision requirements of tatirelin tablet raw material screening. Therefore, we propose a raw material screening device for tatirelin tablet production. Utility Model Content

[0004] This invention provides a raw material screening device for the production of tatirelin tablets, which solves the problem of inconvenient screen disassembly and replacement.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides a raw material screening device for the production of tatirelin tablets, including a screening box, both ends of which are provided with guide ports, and the two sides of the screening box are respectively provided with a shaking port and an inlet / outlet, and the screening box is provided with a screening mechanism inside. The screening mechanism includes a screening box, which is movably installed inside the screening chamber. A base is fixedly installed at the lower end of the screening box. The surface of the base has evenly distributed screening holes, and an air chamber is opened inside the base. An air bladder tube is installed inside the screening holes. An air pump is fixedly installed on the outer surface of one side of the base. A shaking mechanism is provided on the outside of the screening chamber.

[0006] The above technical solution achieves flexible adjustment of the effective aperture of the screening hole by combining the "screening hole + air bladder tube + air pump", thus addressing the defect of the non-adjustable filter holes in traditional devices. On the other hand, the movable installation of the screening mechanism and screening box, along with the design of the shaking ports and inlet / outlet on both sides of the screening box, provides a structural foundation for subsequent shaking screening and disassembly and cleaning of the mechanism, balancing screening accuracy and operational convenience.

[0007] Furthermore, the screening box and the base both enter the screening chamber through the inlet and outlet, and the air bladder tube is fixedly installed with the base.

[0008] The above technical solution clarifies that the screening box and base can enter and exit the screening box as a whole through the inlet and outlet, solving the problem of cumbersome disassembly and assembly of traditional fixed screens, and facilitating thorough cleaning or replacement of the screening mechanism in the later stage; at the same time, the fixed installation of the air bladder tube and the base ensures that the position of the air bladder tube is stable when adjusting the aperture, avoiding the impact of loosening on screening accuracy and ensuring the consistency of screening of tatirelin tablet raw materials.

[0009] Furthermore, one end of the air pump is fixedly connected to a connecting pipe, which extends through the base into the interior of the air chamber and is connected to the air chamber.

[0010] The above technical solution constructs an airflow transmission channel of "air pump - connecting pipe - air chamber", which allows the gas output from the air pump to stably enter the air chamber, thereby providing power for the inflation / deflation of the air bladder tube. This channel design ensures leak-free airflow transmission, guarantees the synchronicity and controllability of the air bladder tube's expansion / contraction, and enables precise adjustment of the sieve aperture, meeting the particle size screening requirements of different batches of raw materials for tatirelin tablets.

[0011] Furthermore, an external air pipe is fixedly connected to the other end of the air pump, and the base is movably installed with the screening box.

[0012] Through the above technical solution, the external air pipe can be connected to an external air source or control equipment to achieve flexible control of the air pump supply pressure, thereby accurately controlling the expansion degree of the air bladder tube and improving the orifice adjustment accuracy; the movable installation of the base and the screening box further enhances the disassembly and assembly flexibility of the screening mechanism, making it easy to quickly remove the base during cleaning, reducing the risk of raw material residue and cross-contamination, and meeting the cleanliness requirements of pharmaceutical production.

[0013] Furthermore, the shaking mechanism includes a top column, which is fixedly installed on the outer surface of one side of the screening box. A shaking column is provided on one side of the top column, and a rotating column is fixedly connected to the lower end of the shaking column. The output end of a drive motor is fixedly connected to the bottom end of the rotating column. Evenly distributed telescopic springs are fixedly installed on the outer surface of the other side of the screening box. An opening and closing cover is provided inside the inlet and outlet.

[0014] Through the above technical solution, the drive motor drives the rotating column and the swaying column to rotate. The swaying column and the top column work together to move the screening box. At the same time, the telescopic spring achieves the reciprocating swaying of the screening box through elastic reset, forming a highly efficient swaying screening action, which solves the problems of incomplete screening and low efficiency of traditional screening devices. The opening and closing cover can close the inlet and outlet during the screening process to prevent raw material splashing. At the same time, it can be opened when disassembling and assembling the screening mechanism, taking into account both safety and operability.

[0015] Furthermore, support frames are fixedly installed on the outer surfaces of both sides of the screening box, and the upper surface of one of the support frames is fixedly connected to the drive motor. The swaying column has an eccentric structure.

[0016] Through the above technical solutions, the support frame provides stable support for the screening box and drive motor, avoiding positional displacement caused by vibration during equipment operation and ensuring screening accuracy; the shaking column is designed with an eccentric structure, so that it can generate periodic thrust on the top column when it rotates, thereby driving the screening box to reciprocate and shake, clarifying the source of shaking power, ensuring stable and sustainable shaking screening action, and improving the screening efficiency and uniformity of tatirazole tablet raw materials.

[0017] Furthermore, the telescopic spring is provided with a telescopic column inside, the telescopic column is fixedly connected to the screening box, the opening and closing cover is hinged to the screening box, and a latch is provided at the connection between the opening and closing cover and the screening box.

[0018] Through the above technical solution, the telescopic column can limit the deformation direction of the telescopic spring, prevent the spring from shifting or twisting during reciprocating swaying, and ensure the stability of the swaying trajectory of the screening box.

[0019] Furthermore, a collection box is provided at the lower end of the screening box, and the collection box is connected to the screening box.

[0020] Through the above technical solution, an integrated "screening-collection" process is constructed. Qualified raw materials after screening through the screening holes can fall directly into the collection box without stopping the machine to transfer the raw materials, solving the problem of traditional equipment requiring interruption of material collection and ensuring production continuity. At the same time, the independent setting of the collection box facilitates the centralized processing of qualified raw materials in the future, reducing losses and pollution during the raw material transfer process, and improving production efficiency and raw material utilization.

[0021] The above-described solution of this utility model has at least the following beneficial effects: This invention establishes an adjustable sieve aperture control system by incorporating an air pump, connecting pipe, air chamber, and air bladder tube. The air pump delivers gas to the air chamber through the connecting pipe, driving the air bladder tube to expand or contract within the sieve aperture. This allows for precise and flexible adjustment of the effective aperture size, adapting to the particle size requirements of raw materials for different batches and processing stages of tatirelin tablets. It completely solves the problems of fixed and unadjustable filter apertures and frequent screen replacements required in traditional devices, improving equipment versatility and sieve accuracy, and ensuring that the raw material particle size meets the specific standards for tablet compression.

[0022] This invention achieves complete disassembly and assembly of the screening mechanism by setting up an inlet / outlet, an opening / closing cover, and a movably mounted screening box and base. The screening box and base can be quickly removed or installed through the inlet / outlet, and the convenient opening / closing cover significantly reduces the difficulty of cleaning and replacing the screen; at the same time, it reduces the residue of raw materials in the device and avoids cross-contamination between different batches of drugs.

[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] like Figures 1 to 4 As shown, an embodiment of this utility model provides a raw material screening device for the production of tatirelin tablets, including a screening box 1. Both ends of the screening box 1 have guide ports 15, and the sides of the screening box 1 have shaking ports 13 and inlets / outlets 14, respectively. A screening mechanism 2 is installed inside the screening box 1. The screening mechanism 2 includes a screening box 21, which is movably installed inside the screening box 1. A base 22 is fixedly installed at the lower end of the screening box 21. The surface of the base 22 has evenly distributed screening holes 221, and the interior of the base 22 has an air chamber 211. An air bladder tube 23 is installed inside the screening holes 221. An air pump 24 is fixedly installed on the outer surface of one side of the base 22. A shaking mechanism 3 is installed on the outer side of the screening box 1. The screening box 21 and the base 22 both enter the screening box 1 through the inlets / outlets 14, and the air bladder tube 23 is fixedly installed to the base 22. One end of the air pump 24 is fixedly connected to a connecting pipe 241, which extends through the base 22 into the air chamber 211 and is connected to the air chamber 211. The other end of the air pump 24 is fixedly connected to an external air pipe 242, and the base 22 is movably installed with the screening box 1.

[0027] In this embodiment of the invention, the raw material enters the screening box 21 through the feed inlet 15 at one end of the screening box 1. Based on the required particle size of the tatirelin tablet raw material, gas is supplied to the air pump 24 through the external air pipe 242. When the air pump 24 delivers the gas to the air chamber 211 through the connecting pipe 241, the air pressure inside the air chamber 211 increases, pushing the air bladder tube 23 to expand within the screening holes 221, thus reducing the effective aperture of the screening holes 221. Conversely, when the air pump 24 evacuates air, the air bladder tube 23 contracts, increasing the effective aperture of the screening holes 221, achieving precise aperture adjustment. After screening, the opening and closing cover 34 of the inlet and outlet 14 can be opened to remove the screening box 21 and base 22 as a whole, facilitating cleaning of the screening holes 221 and the air bladder tube 23 and preventing raw material residue.

[0028] like Figures 1 to 4As shown, the shaking mechanism 3 includes a top column 31, which is fixedly installed on the outer surface of one side of the screening box 21. A shaking column 322 is provided on one side of the top column 31, and a rotating column 321 is fixedly connected to the lower end of the shaking column 322. The output end of the drive motor 32 is fixedly connected to the bottom end of the rotating column 321. Evenly distributed telescopic springs 33 are fixedly installed on the outer surface of the other side of the screening box 21. An opening and closing cover 34 is provided inside the inlet and outlet 14. Support frames 12 are fixedly installed on the outer surfaces of both sides of the screening box 1. The upper surface of one support frame 12 is fixedly connected to the drive motor 32. The shaking column 322 has an eccentric structure. A telescopic column 331 is provided inside the telescopic spring 33. The telescopic column 331 is fixedly connected to the screening box 21. The opening and closing cover 34 is hinged to the screening box 1, and a latch 341 is provided at the connection between the opening and closing cover 34 and the screening box 1. A collection box 11 is provided at the lower end of the screening box 1, and the collection box 11 is connected to the screening box 1.

[0029] In this embodiment of the invention, the drive motor 32 is started, and its output end drives the rotating column 321 and the eccentrically shaped swaying column 322 to rotate. During the rotation of the swaying column 322, it periodically pushes the top column 31, causing the screening box 21 to move to one side and compress the telescopic spring 33. When the swaying column 322 rotates to disengage from the top column 31, the telescopic spring 33 resets under the action of elastic force, pulling the screening box 21 to move in the opposite direction, forming a reciprocating swaying motion. The telescopic column 331 can prevent the telescopic spring 33 from deviating during swaying, ensuring the stability of the movement trajectory of the screening box 21. During the screening process, the raw material residue falls into the collection box 11 below for collection, and the raw material that passes through can be taken away from the guide port 15 at the other end of the screening box 1. The opening and closing cover 34 is locked by the latch 341, which supports the telescopic spring 33. The support frame 12 provides stable support for the drive motor 32 and the screening box 1, reducing the vibration of the equipment during operation.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
